Intel turboboost is not the same as AMD PBO... Instead of letting the cpu use ~2x the rated power ("TDP") in tau periode you can tell the cpu to boost maximum in a preset packet power target, and pbo will never go above it.
6 cores limited to 65w package power with PBO curve optimizer

16 cores limted to 120w package power with PBO curve optimizer

PBO normally controll 3 power limiters, edc tdc and ppt.
If you set PPT to a high/unlimited number the cpu will try to boost as high as it can with no regards to power (ppt), with the only limiting factors being temp and FIT value. But it can just as well be used like i showed above where you set a maximum packet power target and it will always stay below it.
